ADJUSTABLE UNIVERSAL WRENCH FOR. AUTOMOBILES, TRACTORS, .AN-LD THE LIKE.

Application filed December 1-, 1925. Ser-ia1 No; 72,430.

By invention. pertains to improvements in adjustable universal wrenches for automobiles;,tractors, and the like.

The object of: m invention is to produce a wrench of the c aracter described which will be new, novel, and of utility, and, be cheap, durable and efficient; easily and quickly fitted and adjusted to any kind of a nut; easily and quickly adjusted to be Worked: in; any lar-lyincramped and inaccessible positions and where: space is limited.

Other :objectsand advantages of the invention will bemore-particularly set forth and shown inthe ensuing description and accompanying one-page drawing; of which,

Figure 1 is an elevational view of the-device showing in the dotted portion the position of. the handleand crank rod when placed in a; stationary position.

Figure- 2 isa perspective view of a fragmentary portion of the device showing more plainly the, position of the handle crank and crank rod: when placed in a stationary position..

Figure 3is a perspective View of a key Y member vfor adjustablyconnecting-the nut holding: member-withv theshank of the bevel gear member'and, with the universal joint, andwvith; a. standard or other socket.

Figured is] an: elevation view of, oneof the bevel gear meinbers and showing another key means of connectingthenut hold- 111;; member therein, and to the universal joint,;and1 sockets.

Figure 5 :is a perspectiveview'of a standand socket.

Like characters ofreference designate like parts inall thefigures.

In the accompanying drawing in which is illustrated the preferred: embodiment of the invention, 1 designates the handles, 2 the crank, and '5 the shank connecting; the handle and crank: to the other working parts; 3-: designates a round portion-near the outer end of the shank 5 taking abearing and.rrevo'lving in cla-sp;311 on the outer end 29 of arm 26 held thereto by screw 30; a portion 4 of said shank 5 is squared and is adapted to be inserted in and held in place in groove 28 in the upright portion 27 of the rigid arm 26. Said shank '5 is rigidly connected at one end 6 to the first bifurcated section 7, 8, of the universal joint.

kind of a; position, particu- The other portions. ofthe universal joint 9:, 10, 11, 12, are connected to said first section 7, and to .a bevel gear 18 bya short shank 13,. said shank being held in place byn'a compressionring 14 fitting in a groove as is shown at -32. Said shank 13 :takes a bearing inaa perforation in an. upstanding holding member 15 which .is fastened-to said rigid member, 26. .by a screw member 17 through an: arm=.16 oflsa-id holding member 15. The outer end of said rigid-arm 26 has a boss 25 thereon havinga perforation therethroughat. right angles to-the length of-said rigid arm. "A second bevel gear, 19 meshing with bevel gear. 18 has iashort shank 23 integraltherewitlnand takes a. bearing in said perforation through the end; of said. rigid arm and is he'ld; in place by acompression ring 24 in a. groove surrounding shank 23 of beveled gear '19 as shown at 32. Said short shank 23 and. bevel gear 19 have a square shaped. perforation therethrough as is shown by the dotted-in portion of the bevel gear in Fig. 4. This is for. the, purposev of holding nut-holding "member 22 at its squared portion 21 as shown at 34K,v 35, 36,101? as shown. by the dotted-in portion above said. bevel 19in perforation .20; This materially assists'inpermitting the nut holding member to be used in different positions for loosening and tightening nuts, and the like. It will be observed the lower bowl of \nut-holding-member 22 has an opening 34 therein to adaptably fit nut 36 audio loosen or tightenthe :same. on .bolt 35.

Eigure3shows another embodiment which may be used tooperatively connect the device to the universal-joint and to' asocket and standard socket for wrench connection, where a reduction of the size is desirable, in

.W-l'llCh. 37 designates'the smaller square end,

39 the squarev lower portion, and 38 the larger square middle shoulder therebetween. The upper portion: 37 has a spring id/anchore-d, tosaid portion-by pin. 41 and the lower portion 39 hasia spring 421 anchored tosaid,,-portion- 39by': pin 43.;gstill another embodimentof connecting the nut turning member is shown at 44: having a shoulder 45 and lower body 46; the holding spring 48 acts on a ball 47 pressing it against the inner square perforation 20.

The crank rod 5 may be made any length as desired but the preferred length would Ill be nine or ten inches. The nut holding member may be adapted to fit any size or any shaped nut and may beplaced either above or below the bevel gear member 19 and into the end of bevel gear member 18.

It will be apparentwhen the nut 36 to be tightened or loosened is fitted with nut turning member22 thereover, handle',jcrai'1k and crank rod members 1, 2 and 5 may be turned while the round portion 3 of crank member 5 is in the bearing or clasp 31, or that said shanlncrank and handle may be raised above the hearing or clasp '31 at any distance desired and at any angle desired and when in such position the same may be turned, thereby turning the universal joint members 7, 8, 9, 10, 11 and 12 acting on shankmember 13 through llOl-Clillg' member 15 turning bevel gear 18; i1 nut turning member 22 is placed in. the end of bevel gear member; 18 the crank works directly through the'universal joint member to turn bevel gear member 18 and nut holding member 22; when it is desired to use nutholding member 22 inconnection with bevel gear member 19 and its shank 23 through the holding member 25,

bevel gear member 18 meshes with bevel gear member 19 and turns nut holding member 22 acting on the nut 36 either tightening or loosening it. It will also be apparent when it'is desired to loosen a nut 01' other holding member which has been fastened exceedingly tighter is rusted so that it is held tightl.y, crank 5 may be lowered and its squared portions securely placed in slot 28 of permanent holding me 'nber 26 and the whole wrench comprised of both the shank, crank and handle and the rigid holding member 26 may be used as one wrench instead of as a revoluble universal joint member of the wrench. When it is desired to use tl'ie'wrench in connection with the various sized sockets or standard sockets the reducing member shown at Figure 3 may be used. c r

From the description of the one-sheet accompanying drawing and the specification the advantages of the making,construction, applying and operating of thewrench, as described, will be apparentrto those skilled in the artto which my invention pertains; but it will be understood that any modifications within the scope of the claimed invention may be made in the construction, opera tion the principle of the invention any of its advantages.

Having thus described the invention, what of a' wrench, as described, comprising ahandle, crank, and crank-rod member, meshed bevelgears with hollowed shanks, a nut holding and interchangeably fitting member revolubly fitting in said hollowed shanks,

and adapted to turn various nuts and other holding means, a long rigid holding member with perttoratedholding meansfor said bevel gears near one end, the other end L-shaped. a holding slot in oneedge of said L-sha'ped portion and a clasp bearing means thereab'ove, the whole adapted to tighten and loosen nutsand other holding means.

*Sl The combination witha universal joint, of a wrench of the character described, comprising a handle, crank, and" crank rodyonc end o'f-said crank-rod being connected to said universal joint, and having a. squared portion near its crank end, said handle, "crank, andcrank-rod being adapted'to rotate said universal joint from various angles,

said squared portion "adapted to fit a slot in a'' rigid member hereafter described, its round portion near crank end taking a bearing in a clamping means in a rigidmemher; .two meshed bevel gears each having hollowed shanks; one of said bevel gears connecting said universal joint; a long rigid holding member having a cross-section perforated holding means in one end, its'other end being L-shaped and having in=one side of said L-shaped portion a. slot adapted to receive and hold the square portion of said crank-rod, and having in the other portion of said L-shaped P01131011 a 'per'foratioir "adapted to receive and hold a clamping member making a bearing for the roundpor- U011 of said crank-rod; a holding member I j "adapted to tighten and loosen nuts and other and application, without departing from holding means and adaptedto be fastened in the hollow shanks of saidbevel gears.
